I guess your one of those who will never quite get it.
If I was looking to save money I'd be much better off buying nearly all my tackle.
I certainly don't save much if any money making my own. Especially if I place a value on my time spent making them.
But I do enjoy the hobby of making tackle. And catching a fish on your own homemade tackle is a pretty awesome feeling.
Once you get the hang of these, which doesn't take long, they don't take long at all to make. And there not that difficult.
The only ones that frustrate me at all are the ones that were not designed for the mold. Those can be a pain to get lined up correctly.
But the standard shapes/sizes are relatively easy and fun to make.
